The Labor-Market Impact of High-Skill Immigration
利用美国博士毕业生调查数据，发现外国博士生涌入特定领域会显著压低同期毕业博士的工资，供给每增加10%工资下降约3%。
The rapid growth in the number of foreign students enrolled in American universities has transformed the higher education system, particularly at the graduate level. Many of these newly minted doctorates remain in the United States after receiving their doctoral degrees, so that the foreign student influx can have a significant impact in the labor market for high-skill workers. Using data drawn from the Survey of Earned Doctorates and the Survey of Doctoral Recipients, the study shows that a foreign student influx into a particular doctoral field at a particular time had a significant and adverse effect on the earnings of doctorates in that field who graduated at roughly the same time. A 10 percent immigration-induced increase in the supply of doctorates lowers the wage of competing workers by about 3 percent.
